Chicago, and Kaskaskia Rivers. Data for the Ohio River System includes the
Ohio, Cumberland, Green, Barren, Kanawha, Allegheny, and Monongahela Rivers.
Other rivers for which data are available are the Arkansas River, which has a
confluence with the Mississippi below the Ohio, and the Tennessee and Clinch
Rivers, which ultimately flow into the Ohio, but also feed traffic to the
Tennessee-Tombigbee Waterway.
